PyZMQ is the Python bindings for ØMQ.
This documentation currently contains notes on some important aspects of developing PyZMQ and
an overview of what the ØMQ API looks like in Python. For information on how to use
ØMQ in general, see the many examples in the excellent ØMQ Guide, all of which
have a version in Python.

PyZMQ works with Python 3 (≥ 3.2), and Python 2 (≥ 2.6), with no transformations or 2to3,
as well as PyPy (at least 2.0 beta), via CFFI.

Please don’t hesitate to report pyzmq-specific issues to our tracker on GitHub.
General questions about ØMQ are better sent to the ØMQ mailing list or IRC Channel.

PyZMQ aims to support all stable ( ≥2.1.4, ≥ 3.2.2, ≥ 4.0.1 ) and active development ( ≥ 4.2.0 )
versions of libzmq. Building the same pyzmq against various versions of libzmq is supported,
but only the functionality of the linked libzmq will be available.

Note

libzmq 3.0-3.1 are not, and will never be supported.
There never was a stable release of either.

Binary distributions (wheels on PyPI
or GitHub) of PyZMQ ship with
the stable version of libzmq at the time of release, built with default configuration,
and include CURVE support provided by tweetnacl.
For pyzmq-15.4.0, this is 4.1.5.
